damasa, I'm so sorry for your loss.
I once had to talk someone out of committing suicide. Thankfully, I was successful... but although I can't fully know the pain you're going through, I have some idea of it.
Take care of yourself. Talk to someone... counselor, friend, clergy member, family member, whatever. Drop a class if doing so will help you concentrate on your remaining classes. Take the time you need to heal.
Take care
